Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter device may determine that a criterion relating to semi-persistent scheduling (SPS) is satisfied, wherein the criterion relates to packet arrival times for SPS transmission; and trigger an SPS resource reselection based at least in part on determining that the criterion is satisfied. Numerous other aspects are provided.

This disclosure provides a method and apparatus for transmitting and receiving time division duplex configuration indication information and a terminal. The method for transmitting time division duplex configuration indication information includes: transmitting a first synchronization signal block (SSB), where the first SSB includes a physical broadcast channel (PBCH), the PBCH carries time division duplex (TDD) configuration indication information, and the TDD configuration indication information includes: TDD configuration pattern quantity indication information, periodicity indication information and uplink slot quantity indication information.

UE performs operations including: receiving a TDD UL-DL configuration and an SPS configuration; performing SPS PDSCH reception on the basis of the SPS configuration; and transmitting an HARQ-ACK for the SPS PDSCH reception. The transmitting of the HARQ-ACK for the SPS PDSCH reception may include transmitting the HARQ-ACK for the SPS PDSCH reception on a second PUCCH resource that satisfies conditions, on the basis that a first PUCCH resource for the HARQ-ACK for the SPS PDSCH reception does not satisfy the conditions. The conditions may include that: i) symbols of a corresponding PUCCH resource do not include symbols indicated in downlink by the TDD UL-DL configuration; and ii) a time from a last symbol of the SPS PDSCH reception to a start symbol of the corresponding PUCCH resource is greater than or equal to a predetermined minimum time.

Disclosed in the present application are an information transmission method and apparatus, used for feeding back hybrid automatic repeat request-acknowledge information to a physical downlink control channel (PDCCH) when the PDCCH indicating a semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) release and an SPS PDSCH are transmitted in a same time slot. The method provided in the present application includes when the PDCCH indicating the SPS resource release is received in a time slot in which the SPS PDSCH is needed to be received, determining to feed back the hybrid automatic repeat request-acknowledge information to the PDCCH, and not to feed back the hybrid automatic repeat request-acknowledge information to a predetermined SPS PDSCH feedback in the SPS PDSCHs; and transmitting a hybrid automatic repeat request-acknowledgement sequence including the hybrid automatic repeat request-acknowledgement information of the PDCCH.
